dTf exp data entry

[robert zellmer]

Someone asked about the "additional volume of cyclohexane" in the data
entry program.  That's there in case you had to add 5.0 mL of additional
cyclohexane in trial 3 to keep the solute in solution.  That doesn't happen
often so it's rare that it has to be used.  If you didn't add any additional
cyclohexane enter zero (0.00) for this blank.  You shouldn't have to enter
units since those are generally there already.
